AAC Accident Reports (2020 - 2025) - Exploratory Analysis

Reports and Injuries by State

Top 20 states, 2020–2025

Note that all data is extracted from publicly avalible accident reports from the AAC, and the data is assumed to be incomplete:

• Not all accidents are recorded, or shared with the AAC
• Not all repored accidents have articles that are publicly avalible (Note that the injury totals in this analysis do not match the reported totals in ANAC and generally undercount injury totals)
• The data extraction and tagging process is imperfect

For more information on how the accident risk factors are extraced, see the Article Text Analysis elsewhere in this repo.
